Peregal (fatty alcohol polyoxyethylene ether) is typically a milky white or beige paste to white flaky solid at room temperature and is readily soluble in water. As a non-ionic surfactant, it exhibits stable chemical properties, being resistant to acids, alkalis, hard water, and metal salts, and possesses excellent leveling, penetrating, emulsifying, and dispersing capabilities. Its primary applications are as a leveling agent and emulsifier, widely used in the textile dyeing and printing industry. It also serves as a cleaning agent in metal processing, an emulsifier in the glass fiber industry, a penetrating agent for pesticides, and a general-purpose oil-in-water (O/W) emulsifier in various industrial applications.
